JOHN W. COSGROVE, OF MEDFORD, AND EDWARD ERICKSON, OF BEVERLY, MASSA CHUSET'I'S, .A-SSIGNORS, BY MESNE ASSIGNMENTS. TO UNITED SHOE MACHINERYGOR- POBATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

SHOE-TURNING- MACHINE.

To all whom it may concern:

Be it known that we, JOHN W. CosGRovE and EDWARD ERICKSON, citizens ofthe United States. residing, respectively, .at Medford, Middlesexcounty, and Beverly, Essex county, State of Massachusetts, have inventedcer tain new and useful Improvements in Shoe- Turning Machines; and Wedo hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The present invention relates to turning machines and more particularlyto machines for turning lasted shoes right side out after they have beensewed.

The turning operation as applied to lasted shoes requires a considerableamount of manual efi'ort upon the part of the operator, coupled withskill to prevent in ury to the upper during the turning operation. NVhcnthe turning operation is performed mechanically the operator is relievedof the manual effort, but upon the other hand the machine is unable toproperly compensate for varying lengths and styles of shoes, andfrequently damages the shoe during the turning operation.

The object of the present invention is to produce an improved form ofturning machine which performs the turning operation withoutthenecessity of substantial aid by the operator, and which may be operatedsuccessfully upon shoes which vary constantly in size and shape.

With this object in view the several features of the invention consistin certain novel features of construction, combinations and arrangementsof parts hereinafter (1escribed and claimed, the advantages of whichwill be obvious to those skilled in the art from the followingdescription.

The invention in its most complete embodiment comprises both meansforturning the heel part of a shoe, and means for turning the forepart of ashoe, but it will be understood that while these means are preferablyused in conjunction to perform all of the operations necessary forcompletely turning a shoe it will be apparent that either the improvedheel turning mechanism or the improved forepart turning mechanism may beemployed alone, if so desired. 1

In the illustrated embodiment of the invention the shoe is clamped inthe machine and the heel and forepart are then turned successively bythe turning mechanism. The operative instrumentalities of the machinecomprise lower and upper clamp members 26 and 28, as shown in Figs. 2and 3, a heel form 30 for turning the heel part of the shoe, a forepartform 32 for supporting the forepart while it is being turned, a forepartturning finger 36 for turning the forepart of the shoe, and a forepartgage 34 for automatically regulating the movement of the turning finger.I

The lower clamp member 26 is mounted, as shown particularly in Figs. 4,5 and 6, at the upper end of a square post 38, fixed upon the frame 42of the machine. In order that it may be adjusted, vertically it s.a.1-

Theheel form; is provided with an antifriction roller68 journaled uponthe upper portionand arranged to engage with and roll over the shoeupper. The heel form is pivotally s11 portediat its lower end by lugs 72forms upon a slide, the lugs receivi'n oppositely extending studs 70.The sli e is grooved to receive the post'38, which forms aguidelmembenfor the slide,

finally, in completing the turning operation,

it is desirable to swing the roller forwardly as itnears the end of itspath of movement. To produce these movements the heel form controlled bycam mechanism. For

this purpose a stud 96 projects inwardly fr'om'each side of the member30, and carries a cam roll 98 which' travels in a cam-path 100: formedin one of'a pairof 'c'am plates l The cam Plzittasrest'iii recessesformed" 1n the sides of the post 38, and'are" pivoted o to the post on:studs-104 at their lower ends; The cam paths 100are so formec'l thatas-the 3.0, the cam" rolls 98 are first moved-rearwe rdly, and then,forwardly again, so that slide 74s-rises, carrying with it" the'heclmform the roller 68 follows a path which-swings rearwardly and then'forwardlyaronnd the it u per, i s des'irableto -retnrn the form ina-path to cause'it toclear the shoeupper'."

Under these conditions the cam plates During thisupward movement the arts have the position of, Figs. 4, 51 and 6', 1 1IIWhlCl'I the slide rod'112 is down, so'that the.projectionlltisseateditrthe notch 118 gagement of the projection 116 with the partof the lever immediately below the notch 102 arein 'their' forwardposition, in which the pathof movementof the roll 68 will be inz closeproximity "to the clamp member 26.

When the slide 74"nearly reaches the upper end of itsrmovement; however,the lower unslotted' part ofxthoplate '76" strikes the J 1 g 124;; andflraises the (slide rod 5 112, thus disengaging: the xp'rojectionr 114'!from-1 the notch 118 and btmguigt thezvprog'ectionillfi into engagementwith the notch 120, whereby the lever 106 is swung so as to move the camplates 102 rearwardly, and thus swing the heel form rearwardly so thatthe roller 1 68 is disengaged from the shoe upper. Dur- The constructionof the forepart form is shown particularly'in Figs. 10, 11 and 12. Thisform has a central member or body 128 in the shape of a flat plate whichis fixed at its rear end to a handle 130. The member 128 is providedwith spreader members 134 pivoted upon opposite sides of the body at132. These side members 134 have upwardly projecting lugs at their rearextremities, which are guided upon a pin 136 projecting laterally fromthe handle into slots in the lugs. 1 A spring 138 interposed between therear ends of the side members tends to swing them outwardly to form ayielding wedge shaped member adapted to fit shoe uppers of differentsizes. This swinging movement is limited by engagement of the forwardextremities of the side members with each other, as shown in Fig. 10.This arrangement of parts adapts the forepart form to fit into and fillshoe uppers of a variety of sizes without any preliminary adjustment ofthe parts. The handle 130 Y is supported upon a yoke 140 and is providedwith a headed stud 142, which projects loosely through a vertical slot144 in the yoke 140, this arrangement being such as-to permit asubstantial degree of play between the handle and the yoke to assist inthe introduction of the form into the shoe, as will be hereinafterdescribed. The yoke 140 is fixed to the forward ends of a pair of sliderods 146 which form part of a telescopic arrangement comprising sleeves148 in which the rods slide, sleeves 150 in which the sleeves 148 slide,and sleeves 152 in which the sleeves 150 slide. The sleeves 152 areintegral with two arms 154, and these arms are connected at theirforward ends, as shown in Fig. 10, by a bolt 156 and a sleeve 158, whilethey are integral at their rear ends with a cleft sleeve 160 whichembraces a hollow shaft 162 and is clamped thereon by clamp screws 163.The hollow shaft 162 is concentric with the shaft 54 previouslydescribed, and it provides for a vertical swinging movement of the arms154 by which the forepart form may be lowered into or raised out ofoperative position. The object of the telescopic arrangement abovedescribed is to permit forward and rearward movements of the forepartform such as are necessary in introducing the form to the upper beforeit hasbeen turned, and in permitting the form to follow the movement ofthe shoe upper as it'is turned. The relative sliding movements of therods and sleeves are limited by pins and slots, as shown in Fig. 11. Inorder that the forepart form may be drawn yieldingly in a rearwarddirection, cords 164 are fixed to the rear ends of the rods 146, andthese cords pass over rollers 166 at the rear of the machine, and areattached to weights 168. The operator may easily draw the forepart formforward, however, by grasping, the handle 130, and the weights are onlysufficient to maintain the forepart form in firm engagement With theshoe during the turning oper- I ation. To raise and lower the arms 154and the forepart form at suitable times in the operation of the machine,mechanism shown particularly in Figs. 3 and 10 is employed. At the lefthand end of the hollow shaft 162 an arm is connected by a rod 172 with adistance arm 174 pivoted on the frame of the ma chine. A cam roller 176is journaled at the pivotal connection between the rod and the arm, andthis roller works in a cam path 178 formed in the left hand face of acam disk 180 fixed on the cam shaft 94. Withv this construction,positive up and down movements are imparted to the arms 154 and to theforepart form hereinafter described.

The forepart turning finger 36 performs an operation analogousto that ofthe turning post employed when a shoe is turned by hand, and, it isprovided at its operative for the purpose end, as is common in suchdevices, with antifriction rollers 182 for engagement with the bend inthe shoe sole. The means for supporting and actuating the turning fingerare shown particularly in Figs. 2, 13, 14 and 15. The rear part of thefinger is in the form of a square rod slidingly mounted in alongitudinal guideway' in a slide 184. The finger is retained in theguideway by means of three bearing blocks 186, 188 and 2164, fastenedto, the upper surface of the S 1 e.

carrier 190 comprising two parallel arms which form gu1deways for theslide, these The slide 184 moves in guideways in a 170 is keyed, andthis arm 3 arms being connected above by integral yokes 192 and 194beneath which the slide 184 can move. The carrier is provided near itsrear end with oppositely projecting trunnions 196 which are journaled inbearings at the upper end of the frame 42 of the machine, as shown inFig. 2. This arrangement permits the carrier to be rockedvertically fora purpose hereinafter described. The slide 184 is moved in the carrierin a forward and rearward direction, for the purpose of actuating theforepart gage 34 and the turning finger v36. The forepart i gagedetermines the v extent of the advancing movement ofithefinger in orderto automatically govern themovement of 3 the finger to accordwith'difiierent} lengths of foreparts'.

iTo lprovide for an operativeconnection between the slide andthekturning fingera friction dog198 is employed, this dog being pivotedatitsllower end by means ofa pin-BOO-toears depending fromthe slide, andbeing perforatedto embrace the shank Qfjthe turning'finger, When-thisfriction 'dogis swung rearwardly it may grip the by a spring pressedplunger 202 which is turning finger and causethe finger to moveforwardly with. the slider Normally, however, thefriction dog swungforwardly i l'l'illllllltt'fCl inthe bearil'ig-block 204 and inits{forward position the friction dog permlts theturning finger to slidefreely through it.

The friction dog is thrown, into operation by the action of; theforepart gage 34 which issllpported and moved until the gage-contactswith the toe portion ofa shoe which has been-bent back about the turningiron 36.v The forward movement of the gage is vw-fthen ,momentarilyarrested-and the con- I tinned movement oftheshde causes a rela- .,tiverearward movement of the gage to move the'friction dog into an operativeposition.

The gage is mountedon a rod 206 which is slidingly supported near itsforward end in ward movement of the slide rods by engage- ,ment withthebearingfblock .186.

it 15 in operation, a screw-234: is mounted in ,a-lug 236 fixed onthe'sl'eev'e 160 of the arms 154 by whichthe'forepart form is supported.When these arms swing. downwardly the screw 234 is brought intoengagement with a block 232 fixed on the yoke 192 of the [carrier 190,thus'holding the carrier in its de- 1s 1n operative position.

After the shoe has been clamped, and the heel part has been turned, theforepart of the shoe must be swungupwardly' and rearwardly sons todouble the sole over the forward and of the turning finger 36, thefinger at thistime'being in its real-most position.

'Since' the fingeris not at this time clamped to the slidegl84, meansare provided for preventing it from sliding rearwardly. For

rock shaft 240'journaled at the rearof the 'frameof themachine with theupper end of the arm 238 in position to be engaged by the shank oftheturning finger. A second, arm 242 fixed to the rock shaft cooperateswith the rod 244 which slides horizontally inbearrings at the side of'the-f rame, and the for wardend ofthe rod 24-1- is arranged to beengaged by the toggle having arms 56 and "58 when the latter'isstraightened in the operation of clamping the work, as shown in By thesemeans the arm 238 is swung forwardly into operative position and heldthere while the clamp in action,

ot but when the clamp is opened for the removal. of the work the arm"238 is free to so that the operator may thrustthe turningfinger asfar tothe rear asv may benecessary for the convenient refrom theclamp.a I

' Thepower mechanism by whichthe ma chine is driven will now bedescribed. ,The

this purpose an arm 238 is mounted on a a,

cam shaft 94 isprovided, at its left hand ,end,,with swa m v lv24=8wl1ich r with a worm 250 fixed on a power shaft 252. ,port it, thecam disk 290 is not fixed rigidly This power shaft is journaled inbrackets 254 forming part of the frame of the ma-" chine. A conicalfriction clutch member 256 is mounted on the shaft 252, being slidablethereon but keyed to the shaft so as to rotate therewith. The clutchmember 256 coiiperates with a clutch surface formed on a pulley 258which turns loosely on the shaft, and this pulley may be belted to anysuitable source of power. To throw the clutch into and out of operationthe clutch member 256 is provided with a grooved collar 260 with which aforked lever arm 262 coiiperates. This lever arm is fixed on a rockshaft 264 which is provided also with a forwardly projecting arm 266. Alink 268 connects the arm 266 with a bell crank lever 270, as shownparticularly in Figs. 16 and 17, and this lever is pivotally mounted ona lever'arm 274 pivoted on a stud 276 on the frame of the machine. Ahand lever 278, in.-

tegral with the arm 274, extends upwardly at the front of the machinewithin convenient reach of the operator. When the hand lever 278 isswung forwardly the clutch members are engaged and the cam shaft isrotated, and when the'hand lever is released a spring 280, connectedwith the arm 274, returns the parts to inoperative position. In thenormal operation of the machine it is desirable to relieve the operatorfrom the necessity of controlling the clutch constantly through the handlever 278, and accordingly automatic means are provided which hold theclutch in operation during predetermined portions of the cycle ofoperations of the machine, and then automatically disconnectthe clutchand stop the machine at the completion of certain stages in the shoeturning operation. For this purpose the stud 272 which connects the bellcrank lever 270 with the arm 274 is connected integrally, as shown inFig. 18, with a slideway 281 having a T- slot in which a slide block 282is mounted. This slide block is provided with a stud 284 upon which acam roller 286 is journaled. An adjusting screw 288 mounted on theslideway 281 retains the slide block in ad-- justed position in theslideway. The roller 286 cooperates with the periphery of a cam disk 290mounted on a shaft 292 which is journaled in a bearing 294 on the frameof the machine. A gear 296 fixed on the outer end of the shaft 292, isdriven by a gear 298 fixed to the worm gear 248.

The cam disk normally retains the clutch in operative engagement, but isprovided with three depressions 300, 302 and 304, re spectively, andwhen the roll encounters and falls into one of these depressions theclutch is disconnected and the machine is stopped. Since a suddenstoppage would involve a. severe strain on the mechanism, particularlythe cam roller 286 and the parts which supion the shaft 292, but ismounted loosely be- (tween a second disk 306 and a collar 308 which arefixed on the shaft. The cam disk is provided with a pin 310 which isconnected by a coiled spring 312, with a pin 314 on the disk 306,.thesepins and the spring working in a recess'formed in the inner face of thedisk 306, as shown in dotted lines in Figs. 16 and 17 Relative movementof the 'two disks is limited by a pin 316 projecting from the disk 290into a slot 318 in the disk 306. When the cam roller engages one of therecesses inthe cam disk 290 the spring 312 yields and permits a slightcontinued rotation of the shaft 292, until the parts have been broughtto rest by friction and by the action of the spring 312. a

While it'isusually desirable to have the operation of the machinecontrolled by the cam disk 290, it may sometimes be desirable to havethe machine wholly under manual control, particularly where the work tobe performed is of a diflicult character in which injury to the shoe islikely to occur unless the turning operation is performed carefullyunder the supervision of the operator. The bell crank lever 270 isconnected at its upper end with a link 320 having its opposite endpivoted on a pin 322. This pin projects eccentrically from a cylindricalshank 324, which turns in a lug 326 on the frame of the machine, and isprovided with a knurled hand wheel 328 by which it may be turned. A halfrotation of the hand wheel and the shank causes the pin 322 to be swungforwardly or rearwardly, this movement being limited by engagement ofthe pin with a stop lug 330, as shown in Fig, 17. When the parts are inthe position of Fig, 17 the automatic stop mechanism is operative, but

when the pin 322 is swung to its rearward position the bell crank lever27 0 is rocked on the arm 274 to a position such that even when the camroller 286 is riding on the circular periphery of the cam plate 290 thelink 268 is not raised high enough to throw the clutch into operation.In this position of the parts, accordingly, the clutch must becontrolled wholly through manipulation of the hand lever 278.

The operation of the machine as a whole will now be described. With theparts in. the position of Fig. 2, the operator places a shoe in positionbetween the clamp members 26 and 28. At this time the shoe is insideout, and it is placed so that the heel part of the sole rests upon theclamp member 26 with the heel part of the upper de-. pending around thisclamp member and around the heel form. 1 The operator then depresses thetreadle 64, thus bringing the clamp member 28 forcibly down upon thesole, and at the same time lowering the turning finger 36 into operativeposition,

as shovvn for example, in Fig. 7. "The operator then pulls-,the 'handlever 278 forvvardly-, thus disengaging: the roller 286 from' thedepression 300 in the cam disk 290, hereuponthe power inechanismstartsthe rotation ofthe cam shaft. This rotation continues for somewhatlessthana of the cam roller 286 'WlththB 'de ression 302 in the cam disk290. This ena les the I operatorto ascertainif the heelturning quarterof a'turn of the cam shaft, with the result that" the heel form a israised to the position of Figt'T, thus, turning-the heel part of theshoe upper, and] the machine then comes to rest, owing to the engagementoperation has been properlycompleted, and

shown in Fig.8; Holding the upper in this" positionthe hand lever "27 8is again I actuated whereupon: a further partial r0 i tation of the camshaft occurs, which is arrestedtby engagement oi "the cam roller 286-with thethird depression 304 in the cam disk 290." This further partialrotation causes the arms3154 to be sw'ungdownwardly into the position ofFig. 8, thus bringin ment with-the doubled, back forepart of the shoe."The operator grasps the handle 130 and pulls the forepart form forward,so

i that its end may be introducedinto the fore part, and he 'thenthrustsit rear Wardly, as a sistedi by. the Weightsn168, so as to cause it tofully enter and distend the forepart. The machine is then in theposition shown in Fig. 8. ,The 0 erator again pulls the hand lever 27 8and t 1e rotation of the camshaft is then completed. During the firstpart of -this rotation the slide 184 (Fig."15)-is advanced intheicarrier 190, carrying the forepart gage 34 with it, vvhile: theturning finger 36 remains for the moment stationary. As soon as themovement of the gage is arrested by contact with the extremity of'thetoe, as shown in Fig. 8, however, the turning finger is clamped in theslide 184 and parts reach the position shown in Fig. 9, theheel partfOIl'll' having in lthe meantime descended. During, the last'part of thethen moved forwardly with it, thus subending operation whereby i theforepart is turned. During this bending operation the -forepart formholdsthe forepart closeqto the turning finger and. retains'it againstanytransverse movement, but the forepart" is gradually strippedfrom theform'a'nd the movement of thecam shaft the arms 154 are swung: upwardly,thus raising theforepart form to inoperative position, and the machinethen comes torest'. The operator thereupon releases the treadle, thuspermitting the upper clamp member to rise so that the forepart form 32into alin'eecting the sole of the shoe to a progressive the turned shoemaybe removed and re; placed by another shoe.

and operation of thismachine are such as to greatly facilitate the Workof the oper ator While relieving him of the necessity of exerting anystrength in the performance of the turning operation. In the majorityof, shoes the operation maybe entirely automatic after the shoe has beenin-. troduced between the clamp members, exe ceptfifor thembendingbackof the 'forepart and the introduction of the foreparhform; butinthecase of diflicjultworkywhere a certain amount of manipulation is neces-It will be apparent that the construction 7 sary to avoid injury to theupper,'this may I be very conveniently performed, owing to thearrangement" by which the machine is automatically stopped at'suitablepoints in a cycle of operations. Where the Workis so diiiicult that: itis not safe to subject the forep'art to acontinuous and automaticturning. operation, the operator may, as

above described,control the forepart turning operationiby manipulationof the hand lever 278, thus graduating the force applied to the upper asmay be necessary, andin the meantime, if necessary, assisting theturning operation by manipulationof the shoe. ipart gage permits themachine to coni- The automatic operation of-the forepletely turn theforepart of any shoef which maybe placed in the machine, regardlessofthe length of tl'ieforepart, While insuring that the forward movementof the turning finger shall, cease at the moment when the turningoperation has been-completed,

sothatthe shoe is not subjected to any un-T duestrain. Both the heelturning mechanismaud the forepart turning mechanismare employed inconnection with shoes which are sewed around theheel part, but in thecase ofshoes which are sewed only around the shank and forepart the heelturning mechanism becomes unnecessary, and may be removed from themachine or disconnected from the actuatingmechanism. In the case ofshoes of this kind the heeL. part is turned by hand, and this maybe doneeither before orafter the forepart of the shoe hasbeeu turned by theoperation of the machine.

It has been; proposed heretofore-to, turn the forepart of. a shoe upperby means of power actuated machine provided with means for clamping theheel :partof the shoe, andaturningfinger for subjecting the sole toavprogressive'bending action. In such prior machines, however, theforepart has beenJheld in its doubled backposition either by theoperator orby means engaging the forepart from the outside. By the use,of 'a forepart form'for holding" the upper in position duringthe'turning operation, it hasxbeen found thatthe turning operation'isbut it may be embodied in various other,
